Final answer:
A graph with skewness -1.8 would be highly skewed left.
Step-by-step explanation:
A graph with a skewness of -1.8 would be highly skewed left. Skewness refers to the distribution of data and how it deviates from a symmetrical shape. Negative skewness indicates that the tail of the distribution is longer on the left side. In this case, a skewness of -1.8 suggests a significant deviation from symmetry towards the left.
